Building codes save energy efficiency

The adoption to reinforce more stringent building energy codes is the best way to improve energy efficiencyfor new buildings at the lowest cost.However, keeping up and meeting the required building energy codes still pose as a challenge forbuilders and architects.

In the mid-century(1940-70), houses were built with much less attention to efficiency and are costly to upgrade. New buildings are therefore encouraged to be built sustainable so that buyers know they are getting a quality product with low utility bills they can afford for many years to come. Needless to say, building codes and efficiency standards now often serve as the efficiency target for refurbishment or other improvements of existing buildings.

In sectors such as residential and the commercial sector, the major part of energy consumption takes place within the building. Energy used in residentialhousing vary from heating and cooling, ventilation, lighting and also installed equipment and appliances.

Modern energy-efficiency codes provide a minimum threshold that architects and builders can easily gain at a much lower cost and offer the potential chance to save money. Occupants investing in energy efficiency will often recover costs in a short period through lower energy expenses.
